Physocarpus ‘Panther’ (Physocarpus opulifolius ‘Panther’)

‘Panther’ Ninebark (Physocarpus opulifolius ‘Panther’). The Physocarpus opulifolius 'Panther', or 'Panther' ninebark, is a deciduous ornamental shrub highly prized for the exceptional intensity of its dark foliage. This variety forms a dense, rounded bush that fits perfectly into informal hedges, shrub beds, and structured borders. Its deeply cut foliage emerges in spring in very dark purple, almost black, shades, creating a spectacular contrast with light-foliaged plants. In early summer, delicate pinkish-white flowers grouped in corymbs appear above the foliage and attract pollinators.

To plant 'Panther' ninebark, choose a suitable exposure: sun to partial shade. The recommended soil is: ordinary, well-drained soil. Water the root ball before planting it and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again. Spread mulch around the base, leaving the collar clear. Avoid systematic fertilization without considering soil richness. In Quebec, choose a period when the soil is thawed and easy to work with. In hot weather, monitor recently planted plants more frequently.

Allow a width of 1.5 m (5 ft) to organize the space for this plant in the garden. The indicated height of 1.5 m (5 ft) helps choose its position relative to neighboring plants. Keep access to the base to weed, check moisture, and remove damaged parts. Pair this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
